Abstract	本发明公开一种多介质模型的频散曲线求解方法及装置，其中，所述方法包括步骤：根据输入的模型数据自动判断介质模型，并选择相应的振型；在广义反透射系数法的理论框架下，构造所述振型的久期函数族；基于所述久期函数族搜索介质模型中存在的全部振型，将同阶数的振型连接起来，绘制成频散曲线。本发明提供的方法能够灵活处理各种不同的介质模型，并且能够稳定、快速、高精度地计算出用户所需的面波频散曲线，具有很强的通用性。本发明在方法上、可适应的介质模型(5种介质模型，另包括板情况)和介质特殊性上、可求解的振型类型(瑞利波、勒夫波、声波)上都与现有技术不同，这三方面的任意组合均在该发明的保护范围之内。
Other Abstract	The invention discloses a frequency dispersion curve solving method and device for a multi-medium model. The method comprises the following steps: automatically judging a medium model according to input model data, and selecting corresponding vibration modes; under a theoretical framework of a generalized anti-transmission coefficient method, constructing a duration function family of the vibration modes; searching all vibration modes in the medium model based on the duration function family, connecting the vibration modes with the same order, and drawing a frequency dispersion curve. According to the method provided by the invention, various different medium models can be flexibly processed, and surface wave frequency dispersion curves required by users can be stably, quickly, and precisely calculated, so that the method is universally applied; The invention differs from the prior art in the method, adaptable medium models (5 medium models and plate conditions are additionally included), medium particularity, and solvable vibration mode types (Rayleigh waves, Love waves, and sound waves), and any combination of the three aspects is within the protection range of the invention.
